Cloudinary generated hidden input value -

i'm using node.js generate direct upload file tag cloudinary

cloudinary.uploader.image_upload_tag('coverimage', {html: {'class': 'cloudinary-coverimage', format: 'jpg'}}) 

after uploading, hidden input tag auto generated @ end of form:

<input type="hidden" name="coverimage" value="image/upload/v1431361091/bns8et8ksrx3km5esdpj.jpg#d36285fd9bcccd5a2034b22ebf69d867fcee0bbc"> 

i realize input value not public id said in docs, when store in db, not generate proper image

cloudinary.image(abc.coverimage) 

how can image's exact public id in hidden input value?

tl;dr

the format of hidden input tag's value {resource_type}/{type}/v{version}/{public_id}.{format}#{signature}. need public_id, in example bns8et8ksrx3km5esdpj.

details

the value of hidden field includes resource type, version, public id , signature of uploaded image. public_id last part of uri before hash (#).

refer sample code, taken node.js controller code, example of handling upload results (to match example above, image_id below should replaced name designated field, i.e. coverimage):

var photo = schema.models.photo; var photo = new photo(req.body);  var image = new cloudinary.preloadedfile(req.body.image_id); // check image resolved image_id valid if (image.is_valid()){   photo.image = image.tojson();   console.dir(photo.image) } photo.save().then(function(photo){   console.log('** photo saved') }) 

brower side

if need public_id of image following direct upload on browser side, should listen "cloudinarydone" event:

$("body").on( "cloudinarydone", function(e, data) {   console.log(data.result.public_id); });
